There is an issue with gcc 4.6.0 that leads to segfault/assert with mesa
due to ureg_src size, reshuffling the structure member to better better
alignment work around the issue.

7.9 + 7.10 candidate

largely a merge of the previously discussed origin/gallium-resource-sampling
but updated.
the idea is to allow arbitrary binding of resources, the way opencl, new gl
versions and dx10+ require, i.e.
DCL RES[0], 2D, FLOAT
LOAD DST[0], SRC[0], RES[0]
SAMPLE DST[0], SRC[0], RES[0], SAMP[0]

For GL fragColor semantics we need to tell the pipe drivers that the fragment
shader color result is to be replicated to all bound color buffers, this
adds the basic TGSI + documentation.
v2: fix missing comma pointed out by Tilman on mesa-dev.

This fixes crashes with the memory debugging routines on Windows.
NOTE: This is a candidate for the 7.8 stable branch
|
|
It was only used for D3D's REP/END/BGNFOR/ENDFOR. D3D's aL register is
just like another address register now.

Allows one to declare fragment shader inputs with cylindrical wrap info.

Changes in v3:
- Documented the new properties
- Added comments for property values
- Rebased to current master
Changes in v2:
- Caps are added in a separate, subsequent patch
This adds two TGSI fragment program properties that indicate the
fragment coord conventions.
The properties behave as described in the extension spec for
GL_ARB_fragment_coord_conventions, but the default origin in
upper left instead of lower left as in OpenGL.
The syntax is:
PROPERTY FS_COORD_ORIGIN [UPPER_LEFT|LOWER_LEFT]
PROPERTY FS_COORD_PIXEL_CENTER [HALF_INTEGER|INTEGER]
The names have been chosen for consistency with the GS properties
and the OpenGL extension spec.
The defaults are of course the previously assumed conventions:
UPPER_LEFT and HALF_INTEGER.

Allows declaring a contiguous block of immediates. Useful for
relative indexing.

Allows one to declare GS input registers.

For example, we would like to have a predicate and texture token
in one instruction to do predicated texture sampling.
|

Previously ureg would always call the driver's create-shader function. This
allows the caller the opportunity to hold onto the tokens if it needs to
reuse them, eg. to create an internal draw shader.
|
|
Couldn't previously emit these except by calling the opcode-specific helper.
|
|
Avoid the need to emit all constant declarations in order. Makes
referring to a specific constant in the constant buffer much easier.
|
|
Fix ureg_DECL_vs_input to reflect this and fix up all callers.
|
|
Manual merge of ureg changes on the branch. Too much unrelated stuff
for a proper merge.
|
|
Simplifies migration to tgsi_ureg.
(cherry picked from commit f574398c07c41cb8d31249a7186fc178ef7d552a)

|
When translating an incoming shader (rather than building one from scratch)
it's preferable to be able to call a single, generic instruction emitter
rather than figuring out which of the opcode-specific functions to call.
|
|
Could previously emit opcodes with label arguments, but was no way to
patch them with the actual destinations of those labels.
Adds two functions:
ureg_get_instruction_number - to get the id of the next instruction
to be emitted
ureg_fixup_label - to patch an emitted label to point to a given
instruction number.
Need some more complex examples than u_simple_shader, so far this has
only been compile-tested.

|
Also fix a typo in ureg_src().
|
|
This is modelled on the nice & easy-to-use facilities we had
for building shaders in mesa, eg. in texenvprogram.c and friends.
Key points include pass-by-value register structs that can be manipulated
in a functional style, eg:
negate(swizzle(reg, X,X,X,X))
and per-opcode instruction functions, eg:
emit_MOV( p, writemask(dst, 0x1), negate(src));
and similar.
Additionally, the interface allows mixed emit of instructions and decls,
which are sorted out internally to obey TGSI ordering.
Immediates may be emitted at any time and are scanned against existing
immediates to try and reduce redundancy.
Not all TGSI functionality is accessible through this interface, but
most or all of what mesa uses should be.
